Have a stock '01 400ex going to a 416.
have read the 400ex's have a problem with deck hieght of cylinder screwing up compression raitos. Does this affect all bore sizes the same, or not so much on smaller bores? I know it was a huge factor for the 440.
does the wiseco 11:1, and JE 10.8:1 actually achieve the advertised ratio or even close with stock gaskets?
Has anyone actually checked the measurements for final CR after everything torqued down.
I'm trying to go as high CR as I can and safely run 91 octane. I know 11:1 is borerline. So I'm leaning toward the JE.
Hotcam stg.1 going in as well. want lots lowend pull.
